In the case of Safari and most other applications, when you click the red button the window closes but the Safari icon in the Dock has a small white dot under it that means the program is still open. In a few applications like Calculator, closing the window will close the application itself, but usually this is not the case. Unlike in Windows, when you press the red button on a Mac's window it closes the window only, and generally does not close the parent application for that window. As PC users are accustomed to doing, Tim closed all Safari windows, but was stuck with Office still claiming he needed to quit Safari. As part of the installation, Office will install Microsoft's Silverlight Web plug-in and so will require you to close your Web browsers (even though this technically is not needed to complete the installation). MacFixIt reader "Tim" wrote in about this exact experience: when trying to install the latest version of Office on his new Mac the process became hung up when it requested he quit Safari.

There are numerous Mac basics that are covered at Apple's support site, among other places, but one area of frustration that seems to be more common than others (even for relatively long-standing Mac users) is the difference between quitting an application and closing its windows.

Recently we have received a few questions from Windows users who have switched to the Mac OS and who have wondered about some behavior differences between OS X and Windows that can, at times, result in frustrating experiences.
